|---|
| Plasma Membrane | Area that surrounds the cell. |
| Cytosol | Clear viscous liquid that surrounds organelles. |
| Organelles | Structures within cells specialized for certain activities. |
| Inclusions | Material that is stored within cells. |
| Permeable Membrane | Membrane which allows substances to pass through. |
| Semi-Permeable Membrane | Membrane which allows some substances to pass through...not others; not necessarily alive. |
| Fluid Mosaic Model of Membrane Structure | Bilayer of phospholipids with embedded proteins floating in or out it. |
| Cell Membrane | Establishes a boundary between the cell and the surroundings. Functions: Protection & Facilitates Contact Outside the Cell. |
| Active Transport | Requires use of cell energy, fuel, ATP, & Enzymes & cell is ACTIVE participant. |
| Passive Transport | Requires NO cellular energy & cell is PASSIVE. |
| Isotonic Solution | 0.85%-0.9% solution, cell will not be affected |
| Hypotonic | less than 0.85%-0.9%, too little solute, cell will burst. In the case of red blood cells this is called hemolysis (laking. |
| Hypertonic | too much solute (more than 0.85%-0.9%) cell will shrivel (crenation) |
| Purpose of Microvilli | to increase the surface area which facilitates transport processes. |
| Cytosol | A clear viscous liquid, located between plasma membrane and nucleas. Composed of mostly water dissolved inorganic substances, and colloidal organic substances. Functions as a background matrix, supports organelles, medium for chemical reactions, assists waste removal and export of secretory products. |
| Ribosome | The "Dad" of the cell responsible for protein synthesis. |
| Endoplasmic Reticulum | The "Sidewalk" or "Shed" of the cell, responsible for transport, temporary storage, and some synthesis. Two types: rough & smooth. |
| Golgi Complex | Known as the "Mailman" of the cell, resonsible for processing and packaging for exocytosis/secretion and glycoprotein formation. |
| Mitochondria | The ATP "Power Plant" of the cell, it is more numerous in more metabolically active cells, and more numerous in certain portions of cells. |
| Lysosomes | The "Maid" or "Garbage Man" of the cell, complete with decompostion enzymes. A.K.A. "suicide packets" |
| Peroxisomes | The "cleaning fluid" used by the "Maid", contains catalase-an enzyme that breaks down Hydrogen Peroxide and other molecules associated with free radicals. |
| Microfilaments & Microtubules | The "Motor Home Structure" or a cytoskelton, used for support and transport. It's suggested as an intracellular nervous system. |
| Centrioles/Centrosome | The "Mom" of the cell, its functions include cell division & as an organizing center. |
| Flagella | The "Wheels" of the "Motor Home", responsible for movement of the cell. |
| Cilia | The "Movers" of the cell responsible for movement of material past the cell. |
| Cytoplasm | The "Air" inside the "Motor Home". |
| Cell Inclusions | Variably-shaped "blobs" of material inside cells, such as: fat, mucus, hemoglobin, glycogen, & melanin. |
